The power-specific fuel consumption (PSFC) density formula is typically expressed as the amount of fuel consumed per unit of power output and per unit of time. Mathematically, it can be represented as:
Where:
- = Power-Specific Fuel Consumption (units: mass of fuel per unit power per unit time, e.g., kg/kW/hr)
- = Mass flow rate of fuel (units: mass per unit time, e.g., kg/hr)
- = Power output (units: power, e.g., kW)
